Let Inbox Zero goal allow some slack.
A helpful change would be to allow 10 unread emails before BeeMinder fails.
I often check my email from my phone but don't run my full GTD system from it. So it's more anxiety producing than helpful on net to have BeeMinder track inbox zero for me when it will just randomly mark me as failing for checking my email from other devices.
Also, I've tried to set this myself, but the interface is completely inflexible and won't let me edit the goal to be something like "under 10" even right after I've started. Why is there total lock-in immediately while I'm trying to setup a goal? This just punishes me for not knowing how to use the interface (assuming there's actually some way to just have a flat goal setup to begin with... which I can't figure out how to implement if it is possible).
Here's my data for an example of the horrible hacking I've been doing trying to make this work for me:
